PROBLEM TO BE SOLVED: To provide a swing driving device which can efficiently cool a brake device.SOLUTION: A shovel includes a driving source which drives a swing body, a speed reducer which is rotatably provided within a case filled with lubricant and is connected to the driving source, and a brake device having an output shaft side spline formed on an output shaft of the speed reducer and a brake plate having spline teeth engaging with the output shaft side spline. A part of either the output shaft side spline or the spline teeth is lost.

    【課題】ブレーキ装置を効率よく冷却できる旋回駆動装置を提供する。【解決手段】旋回体を駆動する駆動源と、潤滑剤が充填されたケース内に回転可能に配設され、前記駆動源と接続される減速機と、前記減速機の出力軸に形成された出力軸側スプラインと係合するスプライン歯を有するブレーキ板とを有するブレーキ装置とを有するショベルにおいて、出力軸側スプライン又は前記スプライン歯のいずれかに欠歯をが形成する。【選択図】図5
